This is a template that can check whether a given input is a wiki link, and extract the link / text from that link.<br />
<br />
A wiki link is defined as a link that is inserted using <nowiki>[...]</nowiki> for internal links or <nowiki>[[...]]</nowiki> for external links.<br />
<br />
The template takes 1 required parameter (the input string), and 1 optional parameter. The optional parameter can be one of ''link'' (returns the link portion, if applicable) or ''text'' (returns the text portion, if applicable).<br />
<br />
The template can be used with #if to check if the input is an internal wiki link (returns ''1''), external wiki link (returns ''2''), or neither (returns nothing).<br />
<br />
This template probably doesn't work for all variants of wiki links - although it does work with the [http://en.wikipedia.org/wiki/Help:Pipe_trick Pipe Trick].<br />
<br />
